It'll never happen, CPython is the reference implementation and a change as drastic as rewriting all of ceval.c is too drastic for any point release.

Learning category theory is about as important to programming in Haskell as denotational semantics are to programming in C. Which is to say, not very important unless you're interested in deeper computer science.

This is quite unreadable with the low contrast colors and the columns are much too small. If you pick a random paper on the arxiv[1] and imagine how much vertical space it will take to just to show the text you'll see the problem. [1]

This is explicitly not a writeup for beginners ( ergo the title ), it's a side-by-side description of the /very/ general categorical description and how you can model that in Haskell. The three parameter form of morphism comp

With the growing use of LLVM to compile numeric Python down to code nearly as fast as C there should be a lot of new opportunities to replace old Fortran code. Albeit this will probably happen over the next 5 years or so.

Then the author is conflating the term "file manager" with "file system".

Completely sensational, file systems will continue to exist as long as we use storage devices. The end-user interacting with the low-level interface may be phased out though.

Depending on your definition of "real world", Benjamin Pierce (of TAPL fame) wrote a book about typing semantics using Coq. Of interest to compiler designers. http://www.cis.upenn.edu/~bcpierce/sf/toc.ht

It's possible to do most of your work in a functional manner in most imperative languages, including C. Doesn't make them any more functional.

At least in CPython sum() will go through PyNumber_Add over heap allocated Python objects. With numpy.sum, the inner loop of the ufunc is summing over an contiguous block of machine types.

Yes, it is well known that allocating 100000000 PyObjects is slow.

LLVM especially llvm-polly seems to be the state of the art, at least of the open source auto-vectorization routines.
